	 * picker picker弹出选择器
	 * @description 此选择器有两种弹出模式：一是时间模式，可以配置年，日，月，时，分，秒参数 二是地区模式，可以配置省，市，区参数
	 * @tutorial https://www.uviewui.com/components/picker.html
	 * @property {Object} params 需要显示的参数，见官网说明
	 * @property {String} mode 模式选择，region-地区类型，time-时间类型（默认time）
	 * @property {String Number} start-year 可选的开始年份，mode=time时有效（默认1950）
	 * @property {String Number} end-year 可选的结束年份，mode=time时有效（默认2050）
	 * @property {Boolean} safe-area-inset-bottom 是否开启底部安全区适配（默认false）
	 * @property {Boolean} show-time-tag 时间模式时，是否显示后面的年月日中文提示
	 * @property {String} cancel-color 取消按钮的颜色（默认#606266）
	 * @property {String} confirm-color 确认按钮的颜色（默认#2979ff）
	 * @property {String} default-time 默认选中的时间，mode=time时有效
	 * @property {String} confirm-text 确认按钮的文字
	 * @property {String} cancel-text 取消按钮的文字
	 * @property {String} default-region 默认选中的地区，中文形式，mode=region时有效
	 * @property {String} default-code 默认选中的地区，编号形式，mode=region时有效
	 * @property {Boolean} mask-close-able 是否允许通过点击遮罩关闭Picker（默认true）
	 * @property {String Number} z-index 弹出时的z-index值（默认1075）
	 * @property {Array} default-selector 数组形式，其中每一项表示选择了range对应项中的第几个
	 * @property {Array} range 自定义选择的数据，mode=selector或mode=multiSelector时有效
	 * @property {String} range-key 当range参数的元素为对象时，指定Object中的哪个key的值作为选择器显示内容
	 * @event {Function} confirm 点击确定按钮，返回当前选择的值
	 * @event {Function} cancel 点击取消按钮，返回当前选择的值
	 * @example <u-picker v-model="show" mode="time"></u-picker>
